Title: Semiconductor memory device and its manufacture
Inventor: NAKAO HIRONOBU
IPC: H01L27/115
Filed: 1992-12-25
Abstract: PURPOSE:To provide a semiconductor memory device of a FACE structure whose power consumption is small and reliability is improved. CONSTITUTION:The channel region 17 of a selected cell is turned to an on-state by a 15 V applied to a word line. As a 0 V is applied to a drain 3, the 0 V is transferred to the channel region 17 and a writing state is obtained by an F-N tunneling. A selection gate electrode 22 turns a channel region 16 to a non-conducting state and prevents a writing prohibition voltage 7 V which is applied to the drain of a non-selected cell from being transferred to the channel region 17 of the selected cell. Therefore, as writing is performed by an F-N current, the injection efficiency of electrons is high and the deterioration of a tunnel oxide film is avoided.

Title: Heat-exchanger with fins
Inventor: MIYAHARA SATOSHI
IPC: F28F1/32
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To enhance heat transfer rate on the air side by making a slit-like cutback in the surface of fins arranged at a constant interval to pass a gas between them and arranging the cut face of the cutback in parallel with the direction of gas flow thereby accelerating the turbulence effect of the air. SOLUTION: In a heat-exchanger where a gas flowing between fins 5 arranged at a constant interval exchanges heat with a coolant flowing through a heating tube 2, a cutback 7 is made to project above the surface of the fun 5 while directing the cross-section 7' in parallel with the direction of gas flow. When heat is transmitted from the coolant circulating through the heating tube 2 through a fin collar 6 and the fin 5 to the cutback 7 and exchanged with the gas flowing between the fins 5, the gas flow collides against the end face 7" of the cutback 7 and flows to the cutback part of an adjacent cutback 7. Consequently, turbulence effect of the gas flow is accelerated and heat transfer rate is enhanced on the air side resulting in the increase of heat-exchanging amount.

IPC: G06F15/163
Filed: 1993-12-30
Abstract: PURPOSE:To reduce the possibility of misfetching of a confirmed answer packet and to effectively and surely broadcast the data consisting of plural packets. CONSTITUTION:The confirmed answers of the data of a single block (plural packets) which are allocated to all sites are collected based on the hierarchical structure that is defined by the transmission software 5 set on a transmission site. The reception software 10 of the site belonging to the lowest hierarchy sends a confirmed answer to the relaying software 9 set in an intermediate site. The software 9 performs the retransmission processing as necessary and receives the confirmed answers from all sites (54-58) following a site 2. Then the software 9 sends a confirmed answer to a site 1 of a higher hierarchy. The software 5 receives the confirmed answers from all lower hierarchy sites and completes the broadcast transmission processing of a single block. Thus the data consisting of plural packets can be surely and effectively sent to each reception site.

Title: Infrared spectrophotometer
Inventor: WACHI TADASHI
IPC: G01J3/10
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To obtain an infrared spectrophotometer which can eliminate any change in power supply voltage and make the temperature of light source to be constant so as to realize highly sensitive and accurate measurement by adopting a ceramic heater for an infrared light source, changing a commercial power supply into DC, and converting it into AC through a switch transistor thereafter. SOLUTION: The values measured by a voltage measuring means and a current measuring means are used to calculate a power value which is actually given to a ceramic heater 11. A control means sets a pulse width in a manner to set the calculated power to the specified value. When the calculated power value is lower than the specified value, the pulse width is made large, and, on the contrary, it is made small. A pulse generation means 16 gives to a switch transistor a corresponding pulse width, on the basis of the signal given from the control means. Thus, the change in voltage is corrected according to the change in pulse width. The temperature of the heater 11 corresponds with the given electric power, so that it can be controlled at a set temperature by the control means.
